Welcome to the Q&A Forum

Hello Mozzers! Couple of days ago I received a request to start optimizing a wordpress website, the domain itself has been around for around 10-12 years so it's it can be considered as one that has real history behind it.  The page has been moved from HTML/FLASH to wordpress about 3 - 4 years ago and hasn't been any SEO maintenance on it. The site used to rank for first position with several keywords, but now understandably, it has greatly decreased. My main question would be, that when I've checked the root domain's and the subdomain's metrics with MOZ Open Site Explorer, the sub domain (with "www.") showed a PA 40 and 90 external links while the root domain (without "www.") only has 27 PA and 6 External links. I know that the 301 or server redirects only transfers about 90% of the link juice to the targeted URL but the difference between the 2 results seem way too big for me. What do you think? Is this normal?
During future link building is it more beneficial to target the root domain so the page won't lose that "10%" by redirecting the new link from sub-domain to root domain?
Is it possible to get more juice transferred? Thank you very much,
Adam
